68 coronet vs. Roadrunner wheel arch (rear)

[Shark1010]

One of the last metal work repairs on my 68 Roadrunner will be to rebuild the rear wheel arches. They are not reproduced without further quarter and the rest of my quarters are good.

So, does anyone know the difference from Coronets and roadrunners from those two years 68-69. Or Plymouth Bbodies 66-67 vs. 68-69 in respect to the wheel arches.?

I understand I will have to work them in a bit different for seams and such, I'm mainly curious as to whether the curves and widths are similar? (Within the ~1/2in) as I know a local Roadrunner (68) which I can match and build it to if it is fairly similar.
Thanks for any input !

i ask about the others as they are reproduced for just the arch. This is not a show car- more of a driver - but I do wish to get it as close as possible without buying more expensive larger replacements if possible.

Find a good used wheel lip molding and build off of that.

I don't know about the curve angle, but I know on the RR it sits lower and covers more of the tire, whereas the Coronet curve is pretty above the tire at stock height. From the side, it's a fairly noticeable difference. Is that what you're talking about? I don't think they're quite exactly the same.

dodge and plymouth are different
and i don't think they will interchange without some major hacking..

Complete quarter panel, including wheel opening is different. 66-67 is WAY different. When I read the OP, I begin to wonder whether your talking about wheel openings (because it seems so obviously different), or perhaps you're talking about wheelhouses/wheeltubs (??)
